During the past couple of month, the crypto market has been going through two major phases.

The first phase, that took place during December 2017, was a strong uptrend amongst most coins, substantial growth, and almost a non-stop rise.
The second phase, that took place During January 2017, was a consolidation phase, where most coins have been correcting down strongly or consolidating.
But there are coins with a better performance, that have shown great stability and consistency during both phases. While most coins were suffering they proved to be the most stable in comparison to the rest cryptocurrencies.
